IMPROVEMENT IN APPARATUS FOR RECTIFVING SPIRITS.

Specification forming part of Letters Patent No. 156,253, dated October27, 1874; application iiled 1 January 28, 1874. i

To all 'whom it may concern:

Be it known that L'CHARLES B. JARVIS, of Lyons, in the county of Clintonand State of Iowa, have invented a new and valuable Improvement vin theProcess of Rectifying Spirits; andlwdo hereby declare that the followingisa full, clear, and exact description of the construction and operationof the same, reference being had to the annexed drawings, making a partof this specification, and to the letters and figures of referencemarked thereon. v

Figure 4l of the drawings is a representation of an elevation of therectiiier in its proper position, 'and in connection with a goose, Fworm, column, and still.

Fig. 2 is a perspective view of the rectifier,

showing the different parts of the same insidel and out. Fig. 3 is aperspective view of one of the trays used Within the rectifier.

My invention is an improved apparatus for deodorizing, rectifying, andavoring spirits; and consists in the construction and arrangement. ofsaid device, and its adjustment in an intermedial position between thegoose and the worm" of an ordinary distilling apparatus.- more suitablyit may be in my distilling apparatus patented April 27, l869-for thepurpose thereby of producing the finest French or Cologne spirits, or,by processes hereinai'` ter described,^of making and iiavoring Bourbonor rye whisky or gin, all of which is hereinafter more lfully describedand .illustrated by the accompanying drawings, in 'which the sameletters designate identical parts of' the said apparatus in thedifferent gures, respectively.

The letter A represents the rectifier, which is constructed and arrangedas follows: It is either a square or cylindrical vessel, of copper, orits suitable equivalent, and of any suitable size. In this vessel, whichhas one open side, are placed trays B, of sheet copper-or,

if a cylindrical vessel, baskets substituted, of the same metal-of anyrequired number, and at suitable distances one above the other, withtheir outer edges resting upon cleats or any other suitable projectionsfrom the inner surface of said vessel, and upon which said trays may beslidden in or out through the said open side. The sides of said traysare of any suitable height-or, if baskets, of any suitable depthandperforated with holes through their bottoms of anydesired number, andeach about one-eighth of an yinch in size. The letter C represents. thevapor-pipe, leading from the goose to the rectifier A, said pipe havinga branch pipe, D, leading directly from the pipe G into a pipe, E, whichlastmentioned pipe is the one which leads from the rectilier into theworm or iinal condenser. The pipes G and- D have suitable stopcocksattached in positions indicated by the drawings, for purposeshereinafterl mentioned. The letter F represents another small pipe, alsofurnished witha suitable stop-cock, as indicated, and leading directlyfrom the boiler into the rectifier, by which direct -steam may beintroduced at anytime into the latter.

For the convenience ot' sliding the aforesaid trays in and out of therectiiier, it is furnished, on the open side, with an opening andclosing door, G, oscillating upon suitable and strong hinges. The saiddoor has anges ja a, which tightly clasp around the corners on each sideof the opening into the rectifier, when said door is closed. On the,outerside of the rectifier, opposite to the closing edge ofthe door, isa hinged an'ge, b, which, to

gether with the ilanges a a, are pierced, with suitable holes, of'anydesired number,'lfor -the purpose of inserting thumb-screws, with whichthe door G may be closely and strongly fastened over the said openinginto the rectifier.

The door may be rendered still more closely steam-tight over saidopening by any of the usual means for that purpose. I

The `aforesaid trays are iilled evenly with charcoal, in lumps ofsufficient size to prevent their passing through theaforesaidperforations. The filled trays are slidden` into place, ranged asaforesaid upon the cleats, and the door tightly closed over the opening,when the rectifier is ready for adjustment.

Of course, the amount of charcoal used at any one time for `charging thediierent trays vmust be proportioned to the quantity of vaporized spiritintended to come over fromthe still.

This proportion is, after the test of expe,- rience', about one bushelof charcoal'to each and every ten barrels of the run ofthe still.

The rectiiier, constructed and arranged as y above described, is placedbetween the goose goose.

and the worm in any distilling apparatus, as aforesaid, nand properlyadjusted by attaching the pipe C, leading from the goose, either intothe bottom of the rectifier, as indicatedv by Fig. 1 of the drawings, orinto the top of the same, should circumstances so require, in

the worm, and the latter to lead from thc pipe A C into the pipe E, asindicated by said Fig. 1. rlhe steam-pipe F is also connected asillustrated by the same figure.

The-rectifier is now ready for the processes to be performed by itsmeans, which are described as follows: High-wine or raW spiritthe resultof aprevious distillation-is firstl vaporized in the still-of anydistilling apparatus which consists of' a still, .a column, a

A goose, and a worm or final condenser-by` heat applied in any of theusual Ways; and

as said vaporized spirit comes over from the "still, lthrough the columnand the goose, it

parts with the fusel--oils (amylic alcohol) therein contained, saidalcohol being passed back into the column by condensation inthe Thevaporized spirit would then be ready for rectifying, but that the firstportion ofthe Arun of' the still is inseparably comfbined also with therank flavors of the grain or other substances in the still, from Whichor when the aforesaid high-Wine was distilled.

Therefore, this said portion ofthe run-about: .fone-tenth-is passeddirectly from lthe goose into vthe Wormby means of said branch pipe D,and, being prevented from passing into the rectifier by closing thestop-cock in the pipe C, this ruiming isalloWed to continue untilthe-vaporized spirit becomes pure and sweetascertained by testing-Whenthe stop-cock in the pipe D is closed and the one in pipe C opened, andthe said spirit passed directly into the rectifier. It is thereinrectified by its passage-through the lay-ers of charcoal or :any otherequivalent material, and thenv passed through the Worm or finalcondenser `into a separate vessel; prepared for the purpose, having beenconverted by `the above process from a high-Wine or raw spirit into thefinest French or Cologne spirits.

Again, provision is made for another-defect in rectifying, hithertounremedied. After about two-thirds of the aforesaid pure vaporizedspirit -has been passed through the charcoal-in the rectifier, theremainder, by reason kof the force of' the steam and the raisedtemperatnre, again takes on the aforesaid rankV flavors.l So soon .asthis is ascertained-byk v testingthe stop-cock in pipe C yisshut and theone in the branch pipe D opened, and the said remainder of the vaporizedspirit run directly through the Worm in to a separately.

prepared tank ,as commercial alcohol.

rIhus the above described processes, by

-fmeans of the. aforesaid rectifier, constructed,

or, if desired, into certain other spirits, here-- inaft-er named anddescribed; and, lastly, in again preventing the last portion of the saidrun from entering the rectifier, but running it into a separate vessel,as hereinbefore dcscribed, as commercial alcohol. The peculiar featuresof the abovedescribed processes, it will therefore appear, are fullycombined in Vmy rectifier and its attachments, which alone supplies theremedies for defects in rectification, hitherto considered irremediable.

Should it be desired to make Bourbon or rye Whisky instead of theaforesaid Cologne spirits, the same process is used, with the additionof steam turned on directly from the boiler into the rectifier, by meansof the pipe F, for the purpose of reducing the vaporized spirit to therequired strength of the different grades of said Whiskies.

Again, should it be required to make gin, the same process is used asfor Cologne spirits, with the addition of placing one or more layers, bymeans of the aforesaid trays, of' juniper-berries, or their equivalents,Within the rectifier, and passing the vaporized spirit through themafter coming through the charcoal, as hereinbefore described.

The following are the most material and desirable results obtained bythe use of the Yhereinbefore-described rectifier: First, a great savingof rectifying materials; second, en-

-tirely preventing evaporation, which is the cause of great loss ofmaterial in most of the distilleries; third, the charcoal does-notbecome impregnated with the essential oils or bad flavors, andthereforelasts much longer;

fourth, a .much smaller quantity of rectifying material is necessary torectify a much larger quantityof vaporized spirit than by any otherapparatus; fifth, a large amount of dead capital is saved, as hitherto alarge quantity of' spirit had to be used in soaking the charcoal beforerectifyin g. Theref'orev What I claim as my invention, and desire -tosecure by Letters Patent, is-

The rectifier A, constructed, arranged, and adjusted in combination withthe goose and Worm of' the usual distilling apparatus, substantially asand for the purposes specified.

In testimony that I .claim the above I have hereunto subscribed my namein the presence -of two Witnesses. l
